To all whom it may concern:

Be it known that I, MARTIN J .KELLY, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in Sprmg-Cocks, of which the following is aspeoification.

My invention relates to improvements in spring-cocks, and the object ofmy improvement is simplicity and economy in construction and convenienceand efiiciency in use.

' In the accompanying drawing 1 Figure 1 is a side elevation of my.improved spring-cock.

Fig. 2 is a front elevation ofthe same.

Fig. 3 is a sectional view, on an enlarged Fig. 4 is asimilar view ofthe same-with the parts moved to a different posit on. i I

Fig. 5 is a side elevation, and in part broken away, of part of the bodyand connected parts, and on a still furtherv enlarged scale;

Fig. 6 is a sectional view on theline y-y of Fig. 7.

Fig. "7 is a plan view of the spindle memfication shown in Fig. 8.

Fig. 10 is a front elevation of the valve seat member shown in Fig. 9.

Fig. 11 is a plan view of the same.

Fig. 12 is a sectional view of a lavatory cock having the operatingparts made according to my invention, and on the same scale as Fig. 8.

Fig. 13 is a similar-view of a faucet embodying my invention.

My improved spring-cock comprises "a body 10 having on one side an inlet11 and on the other side an outlet 12, and on the upper end a seatinclosing an opening provided with an interior screw thread 13 which isclosed by a cap 14, through which projects a spindle 15. 1

The body 10 is divided by a division wall 16 into two chambers,respectively areceiving chamber 17, on the lower side generallyandconnected with the inlet 11, and a'discharge chamber 18 on the upperside, confor.

nected with the outlet 12, the said division I wall 16 having an opening19 in line with the axisof the cap 14 and spindle 15, the lower side ofthe wall of which opening 19 serves as a valve seat 20.

' The cap 14 is an elongated structure and hasa bore of two diametersthelower and larger portion 21- of which constitutes an extension'of thedischarge chamber 18 and the upper portion-22of which is a fitfor thespindle 15 and serves as a bearing there 1 The lower and larger bore 21serves'as a cam chamber for housing a pair of cotiperating end cams. .1,

One of the said end cams, serving as the upper end cam 23, isintegralwith the cap 14, extending downwardly from the roof of the lateralor'overhanging portion of the larger'bore 21, relatively to the smalleror spindle bearing portion 22, the cam faces. being onthe lower sideand, arranged in V-shape, the same being made duplex, so

that there is a V -shaped;cam face on each side of the axis. I

Opposed tothe upper end cam 23 is a lower end cam 24 that is integralwith the spindle 15, the formof the cam faces there-. on being also V-shaped. WVhile in some cases the end Icammembers may have their opposedcamface's incontactfor effecting the valve movements'desired' and to bedescribed,I have in thepresent case provided special contact balls 26that are supported- .by'thc lower cam 24 and spindle 15 and which makecontact with thecam 'faces of the said upperend cam 23,'during theeffecting of such movement. The said balls 26"are four in number, and

are located in pockets or wells 27, there being'onesuch' pocket and ballat about the middle of each' of the inclined surfaces 28 of the V-shapedcam faces in the said lower cam 24. r r The upper portion-29 of thespindle 15 is a fit in the spindle bearing 22in the cap 14, the middleportion isrelatively enlarged to form the lower end cam 24, and thelower portion 30 is in the form of an extension, below the lower end cam24, and serves as a valve stem, extending through the valve opening 19and below the valve seat 20.

Thelower end portion 31 of the valve stem 30 is screw threaded and hasmounted thereon, and secured in-place by a nut .32, a

valve 33, positioned below the valve seat 20, suitably to cooperatetherewith.

A spring 38 has the upper end engaged with the valve 33- and thelowerend engaged with a seat 3-1 provided in the lower,

end of the body 10 and the said spring tends to hold the valve engagedwith its seat, and

also holds the opposed cam surfaces in enheld inplace by. a. lock nut 37passes .up-

wardly through the seat 34 and serves asa stop, in engagement with theValve stem 30, to iimit'the downward movement ofthe said stem'and thelower cam member 24: connected thereto.

In operation when the spindle 15 is turned from :the normalposition thecooperation of the scam faces serves toforce the valve 33 from its seat,in opposition to. the spring 38, and-whenzthe spindle is released thespring will :tendto restore the parts to the normal position.

The spindle 15 is provided adjacent the upper end with a groove 45 inthefside wall which engages with a key &6, as'shown in Fig; 4, toholdlthe said spindle'away from the normal position and thereby hold thevalve open,= in the depressedposition. The key 46 is pivoted by means-ofa pin 47 in a slot rs, suitably to beswung in a vertical plane into andaway fromthe engaging po sition, the said slot 48 being provided-in atop cap 49that covcrsthe upper end portion-i0 of the cap 14. The saidtop cap 49 is secured to the upper end portion 40 by means of a screwthread tl.

In some cases. an outlet 52 is provided .in the'cap 14- and provision ismade for connecting the samewith the discharge chamber 18 anddisconnecting the same therefrom by a set of grooves, comprising" alower groove 53 across the lower cam memberfl l: and alongitudinalgroove 54 connecting therewith on the periphery of the; spindle 15 and alateral or: branch groove-55 connectingthe upperend of the groove53vwith the dischargeopening -52.

The small outlet 52 and the connecting grooves areprovided in specialcases to serve asaventg connection or outlet for the dischargechamber 18and the portion'of the iipinggsystem connected thereto through thedischarge opening 3 12.

It willbe noted as-shown and described that when the va'lveis' in theclosed positionptl're'pressure offthe Water tends to hold theiavalve insuch. closed position and the opening. is. effected, by I moving, thevalve against.usuchmnressure:,

In themodification shown in Figs. 8 and 9 the bottom of the body 10 isclosed or integral with the general body structure, and theseat 3 L"forth-e spring 38 is provided on the upper side thereof, and the stop 36for the end of the stem 31 and the spindle member 15 is in the form ofan integral'knob or protuberance on the said-up per side of the bottom35 As the valve 33 is larger than the seat 20 as in the otherconstruction described I provide the said valve seat20 on the lower sideofiaremovable structure in the form of the removable valvescatmember 56which is secured in place .in the "body 10 by means of a screw thread57provided in a'suitable opening in :the division wall 16 The valve seatmember 56 comprises an annula-ribody-portion; the exterior of whichisprovided;with.the said th-read'57, and at the upper :end there. is anannular, laterally eXtendingo-r overlapping flangeq58 suitable forengaging with a seat 59 onlthe division wall 16, either directly'orpreferably-with a packing washer 6O interposed therebetween. The upperside of the'flange, or head. 58is provided with cross-slots 61 indiametral alinement and forming (essen tially a screwdriver slotforreceiving a screw-driver device for squaring the valve seat member 56 inplace.

Such screw-'clriver device I provide in the forinof a diametral rib 62on the spindle 15 at lower side of the lower cam member 24.

In the; assembly thevalve seat member 56 is mounted loosely on the lowerportion of the-spindle member 15 between the integral lower cam member 2and the valve 33 The spring 38 is placed on its seat 34 andtnenwthespindle member 1f with the valve seat member 56 mounted thereonas described is inserted in the body10,,an'd the valve seat member 56screwed into-place. The lower end 63 of the valve-seat member 56 istapered suitably to facilitateengagement of the threaded portion 57.

After the spindlemember 15 and-valve seat @member 56 are in place thecap 14-? is placed in position.

The-construction of the faucet style of cock shown in Fig. 13corresponds to that shown in Fig. 9, difi'eringtherefromin dimensionsthe same having a removable valve seat member 56 cooperating withthevalve 33*, mountedgon the spindle 15".

In thelavatory cock shown in. Fig. 12 the inlet 11? to the body 10 is atthe lower; end thereof. and except for the feature and changes that areinvolved with :the same, the internal structure corresponds :to' that'ofthe faucet vstyle shown in Fig. 13.

The inlet 11 is positionedat the lower side of thexbase 35' ofthe bodyproper 10, which base is provided with a laterally ex tendingsupportingjfiange' 63, and the: said inlet 11 is bridged by a spider 64supporting the stop 36 that cooperates with the lower end of the spindle15 to limit the downward movement thereof.

Below the inlet 11 and base 35 is a downward, sleeve-like extension 67threaded at the exterior to receive a clamping nut 66, and also toreceive at the lower end the screw threaded nut member 68 of a union 69.lower end in the form of a sleeve member which constitutes the inletproper.

In the various styles disclosed the valve is opened against the pressureof the water, and when closed the said pressure of the water tends tohold the valve in the closed position. I

Also the valve is spring closed, the handle and end cam features beingbrought into play merely for effecting the opening of the valve.
